10 Claims, No Drawings FINISHING AGENTS FOR TEXTILES This inventionrelates to compositions useful as finishing agents for textile articles.More specifically, this invention relates to compositions useful asfinishing agents for textile articles containing polyester fibers. Thecompositions of this invention are useful for modifying the hand orhandle of polyester fabrics as well as reducing the tendency of knittedand woven fabrics constructed from texturized polyester yarns to snag orpick on sharp or abrasive objects during wear.

Knitted and woven fabrics constructed from texturized polyester yarns oryarns containing polyester fibers have the unfortunate tendency to snagor pick during normal wear. Snags detract from the appearance ofgarments and shorten acceptable wear-life. The hand or handle ofpolyester-containing fabrics, particularly those containing onlytexturized polyester yarns, is also difficult to modify permanently withconventional finishing agents in that many have a tendency to lose theirfinish during dry cleaning and washing procedures.

lt is an object of this invention to provide compositions useful asfinishing agents that impart a durable handle to textile articlescontaining polyester fibers and that reduce the tendency of fabricsconstructed from textured polyester yarns to snag 'or pick on sharp orabrasive objects in wear. It is a further object of this invention toprovide crosslinkable, aqueous blends when applied to fabrics whichprovide excellent adhesion to polyester and many other fibroussubstrates, good wash resistance, excellent dry cleaning resistance, andexcellent handle. It is a further object of this invention to providenovel compositions which have applications in the areas of spray bindingfor staple fibers as a nonwoven fabric binder, a knit fabric handbuilder, an antipick resin, a flocking adhesive and a fabric finish.

Water-dissipatable copolyesters derived from at least one dicarboxylicacid component, at least one diol component, at least 20 mole percent ofsaid diol being a poly(ethylene)glycol, and a difunctional monomercontaining a -SO M group wherein M is a monovalent alkali metal aredisclosed in US. Pat. Nos. 3,734,874, 3,546,008 and 3,779,993.Furthermore, aqueous dispersions of coating compositions consisting ofthe above type copolyesters dispersed together with amelamine-formaldehyde resin have been sold under the trade name ofWDX-743, WDX-744 and Eastman Binder DFB, products of Eastman KodakCompany. These aqueous coating compositions, however, provide coatingswhich produce a very stiff, unpleasant hand or feeling to polyesterfabrics. The compositions of this invention improve over the prior artcompositions in that they impart a durable handle to textile articlesand have advantageous picking and snagging properties.

In one aspect of this invention there is provided textile finishingagents which are prepared from aqueous blends of l a water dissipatablelinear copolyester of the type disclosed in US. Pat. No. 3,734,874 andUS Pat. No. 3,546,008, (2) an amino crosslinking resin, and (3) apolyoxyethylene containing glycol. An acid or latent acid catalyst isused to effect a thermallyinduced crosslinking reaction which, whencarried out on the surface of textile fibers, leaves a water-insolublefilm having good adhesion to textile fibers. The compositions thusformed, which partially or wholly covers the fiber surfaces and in someinstances forms interfiber bonds, imparts an illusion of added weightand bulk to the fabric and reduces the tendency of the fabric to snag orpick. The handle of the finished fabric may be controlled by judiciousselection of the ratio of the three components in finishing agentformulation as hereinafter described.

The compositions of this invention can be more specifically defined asan aqueous blend of the following components:

I. from about 50 to about 85 (preferably about to about parts by weightof a linear, waterdissipatable polyester derived from components (A),(B) and (C) as follows:

2. from about l5 to about 50 (preferably about 20 to about 30) parts byweight of at least one waterdissipatable amino resin having atleast tworeactive groups, said resin being selected from the group consisting ofmelamine-formaldehyde condensates, methylated melamine-formaldehydecondensates, urea-formaldehyde condensates, methylated urea-formaldehydecondensates, guanamineformaldehyde condensates and methylatedguanamine-formaldehyde condensates; and

3. from about 10 to about (preferably about 10 to about 60) parts byweight of a water-dissipatable nonionic linear poly(oxyethylene)containing glycol having the formula (I) HO-(-CH CH O)-,, ,H wherein mis an integer from about 4 to about I50,

wherein x, y, and z are integers, the sum of which results in a glycolhaving a molecular weight from about 1,000 to about 14,000, and theratio of x z to y is such that the hydrophile/lipophile balance is fromabout 4.5 to about 30.5.

ln one preferred embodiment of this invention the above aqueous blendscontain about 0.5 to about 50 percent by weight of combined solidssupplied by components l), 2) and 3).

The dicarboxylic acid component (A) from which the linearwater-dissipatable polyester component of this invention is prepared canbe any aliphatic, cycloaliphatic, or aromatic acid. Examples of suchdicarboxylic acids include oxalic; malonic; dimethylmalonic; succinic;glutaric; adipic; trimethyladipic; pimelic; 2,2-dimethylgultaric;azelaic; sebacic; fumaric; maleic; itaconic;l,3-cyclopentanedicarboxylic; 1,2- cyclohexanedicarboxylic, 1,3-cyclohexanedicarboxylic; l,4-

onic; 4,4'-sulfonyldibenzoic; and 2,5-

naphthalenedicarboxylic acids. In a preferred embodiment of thisinvention isophthalic acid is the dicarboxylic acid utilized. Ifterephthalic acid is used as the dicarboxylic acid component of thepolyester, especially good results are achieved when at least five molepercent of one of the other acids listed above is used.

It should be understood that the use of the corresponding acidanhydrides, esters, and acid chlorides of these acids is included in theterm dicarboxylic acid." The esters are preferred, examples of whichinclude dimethyl l,4-cyclohexanedicarboxylate; dimethyl 2,6-naphthalenedicarboxylate; dibutyl 4,4-sulfonyldibenzoate; dimethylisophthalate; dimethyl terephthalate; and diphenyl terephthalate.Copolyesters may'be prepared from two or more of the above dicarboxylicacids or derivatives thereof.

At least about mole percent of the diol component (B) used in preparingthe water-dissipatable polyester component of the invention is apoly(ethylene)glycol having the formula H+OCH CH ),,OH wherein n is aninteger of from two to about ten. Examples of suitablepoly(ethylene)-glycols include diethylene, triethylene, tetraethylene,pentaethylene, hexaethylene, heptaethylene, octaethylene, nonaethylene,and decaethylene glycols, and mixtures thereof. Preferably thepoly(ethylene)glycol employed in the polyester of the present inventionis diethylene glycol, triethylene glycol, or mixtures thereof. Theremaining portion of the diol component is at least one aliphatic,cycloaliphatic, or aromatic diol. Examples of these diols includeethylene propylene glycol; 1,3-propanediol; 2,4- dimethyl-Z-ethylhexanel,3-diol; 2,2-dimethyl-l ,3- propanediol,2-ethyl-2-butyl-l,3-propanediol; 2-ethyl- 2-isobutyl-l ,3-propanediol,l,3-butanediol; 1,4- butanediol; l,5-pentanediol; 1,6-hexanediol; 2,2,4-trimethyl-l ,6-hexanediol; l,2 cyclohexanedimethanol;2,2,4,4-tetramethyl-l ,3-cyclobutanediol; and pxylylenediol. Copolymersmay be prepared from two or more of the above diols.

The third component (C) used to prepare the waterdissipatable polyesteris a difunctional monomer containing a SO M group attached to anaromatic nucleus, wherein M is hydrogen or a metal ion. Thisdifunctional monomer component may be either a dicarboxylic acid (orderivative thereof) containing a SO M group or a diol containing a -SO Mgroup.

The metal ion of a sulfonate salt group may be Nafi,

Li or K".

Other effective difunctional monomers containing a SO M group attachedto an aromatic nucleus include metal salts of aromatic sulfonic acids(or esters thereof). These monomers have the general formula ROOC o-O-Y-SO3 M ROOC/ o SO M group attached to an aromatic nucleus includemetal salts of sulfodiphenyl ether dicarboxylic acids (or estersthereof). These monomers have the general formula wherein R is hydrogen,an alkyl group of one to eight carbon atoms, or phenyl, M is Na Li, orK*, and a is l, 2, or 3. Examples of preferred monomers here aredimethyl 5-[4-(sodiosulfo)phenoxy]isophthalate, dimethyl5-[4-(sodiosulfo)phenoxy]terephthalate, and5-[4-(sodiosulfo)phenoxy]isophthalic acid.

The water-dissipatable polyester should contain at least about eightmole percent of the monomer based on total acid content, with about 10mole percent giving particularly advantageous results. Greaterdissipatability is achieved when the difunctional monomer constitutesfrom about 10 mole percent to about 45 mole percent of the total contentof acid of the polyester.

To obtain the polyester component of this invention, the difunctionalmonomer containing the SO M group may be added directly to theesterification reaction mixture from which the polyester will be made.Thus, these monomers can be used as a component in the originalpolyester reaction mixture. Other various processes which may beemployed in preparing these polyesters are well known in the art and areillustrated in such patents as US. Pat. Nos. 2,465,319; 3,018,272;2,901,466; and 3,075,952. These patents illustrate ester interchange andpolymerization processes.

Whenever the term inherent viscosity (I.V.) is used in this description,it will be understood to refer to viscosity determinations made at 25C.using 0.5 gram of polymer per ml. of a solvent composed of 60% phenoland 40% tetrachloroethane as parts by weight. In addition, whenever theterms dissipatable, dissipated or dissipate," are used in this description, it will be understood to refer to the action of water or aqueoussolutions on the components of the blends of this invention. The termsare specifically intended to cover those situations wherein the solutiondissolves and/or disperses these blends. Furthermore, whenever the wordwater is used in this description, it includes not only aqueoussolutions but also hot aqueous solutions.

In an especially preferred embodiment of this invention thewater-dissipatable polyester component is derived from 90 mole percentisophthalic acid, mole percent of 5-sodiosulfoisophthalic acid, and 100mole percent of diethylene glycol and having an inherent viscosity(l.V.) of at least 0.30 as measured at 25 using 0.50 gram of polymer per100 ml. of a solvent com posed of 60 percent phenol and 40 percenttetrachloroethane. The copolyester useful in this invention may beterminated with either hydroxy or carboxy end-groups. In addition, theend-group functionality of the copolyester, and therefore itscrosslinkability, may be increased by reaction of the high molecularweight linear polyester with trior tetrafunctional hydroxy or carboxycompounds such as trimethylolpropane, pentaerythritol, or trimelliticanhydride in a manner known in the art.

Examples of the water-dispersible amino resins useful in this inventioninclude the melamine-formaldehyde condensates, the methylated (wholly orpartially) melamine-formaldehyde condensates, the ureaformaldehydecondensates, methylated (wholly or partially) urea-formaldehydecondensates, the methylated (wholly or partially) guanamine-formaldehydecondensates, and the like. These amino resins are known in the art andcan be prepared by known means or obtained commercially. The propertiesof these resins, as well as some of their uses in textiles applications,are set forth in Mark, Wooding, and Atlas, Chemical Aftertrealment ofTextiles, John Wiley & Sons, Inc. (1971), pages 267-355. Preferred aminoresins useful in this invention are hexamethoxymethyl melamine (Cymel300, a registered trademark of American Cyanamid Company), partiallymethylated melamine formaldehyde adduct sold also under various tradenames (for example, Aerotex M-3, a registered trademark of AmericanCyanamid Company), and various urea-formaldehyde condensates such asAerotex Resin 802, a registered trademark of American Cyanamid Company.

Examples of poly(oxyethylene) containing glycols useful in thisinvention are those which have an average molecular weight of from 200to about 7,000, the only requirement being that thepoly(oxyethylene)-glycols be dispersible in water. Especially preferredpoly(oxyethylene)-glycols useful in this invention are those having anaverage molecular weight of from about 1000 to about 6000 (eg., havingthe formula HO(CH CH O),,,H wherein n is an integer of from about toabout 130), sold under the trade name Carbowax, a registered trademarkof Union Carbide Corporation. Examples of the specific Carbowaxes usefulin this invention are Carbowax 200, Carbowax 4000, and Carbowax 1000,Carbowax 4000 being especially preferred. Also useful as thepoly(oxyethylene)glycol component of this invention are thewater-dispersible ethylene oxidepropylene oxide block copolymer glycolswhich are also sold commercially under the trade name of Pluronics, aregistered trademark of Wyandotte Chemicals Corporation. These glycolsare the condensates of ethylene oxide with hydrophobic bases formed bycondensing propylene oxide with propylene glycol and have the generalformula H+ocH,CHrmocucHm vocn cumon where .r, y, and z are integers, thesum of which results in molecular weights ranging from about 1,000 to14,000, preferably 3,000 to 10,000. The ratio ofx z/y is such that theHLB (hydrophile/lipophile balance) is from about 4.5 to about 30.5,preferably 6.6 to 24.5. [The HLB of a nonionic surfactant is defined asthe approximate weight percent of ethylene oxide in the surfactantdivided by 5. See W. C. Griffin, J. Soc. Cosmetic Chemists, l, 311(1949).]

Examples of useful Pluronics are Pluronic F38, L35 and P65.

The ratio of poly(oxyethylene) containing glycol to combined parts ofcopolyester and amino resin used in the dispersions of this inventiondetermines the softness of the cured film and therefore the softness ofthe finished textile article. If no poly(oxyethylene)glycol is used, thefinished article tends to be rather stiff and boardy. Softness increaseswith increasing poly(oxyethylene)glycol content. Surprisingly, it hasbeen found that the articles coated with the compositions of thisinvention show better softness or handle properties than the prior artcompounds. In a preferred embodiment of the invention 10 to 60 parts byweight of poly (oxyethylene)glycol per parts of copolyester- /aminoresin is used to produce commercially attractive hands of increasingsoftness.

The optimum ratio of copolyester to amino resin depends upon severalfactors, including amino resin functionality and reactivity, copolyesterend-group concentration and reactivity, and molecular weight andconcentration of poly(oxyethylene)glycol. The copolyester/amino resinratios found useful in practice of the invention range from about 1:1 to6:1, the preferred ratio being about 3:] copolyester/amino resin.

The above components 1), 2) and 3) are, for convenience in commercialhandling, dispersed in enough water to bring the total solids content toapproximately 30 percent. This concentration can then be readily dilutedto the desired level for application to textile substrates when readyfor use. It is desirable but not essential to include 1 to 10 parts (4to 5 parts preferred) of a poly(oxyethylated) alkyl phenol to the 30percent solid dispersion. This type of nonionic surfactant improves thestorage life and electrolyte stability of the formulation and serves asa wetting agent for the substrate. Poly(oxyethylated) alkyl phenols aresold under various trade names, such as Triton, a registered trademarkof Rohm & Haas Company, and Igepal, a registered trademark of CAPCorporation.

To apply a finish of the type disclosed in this invention to a textilesubstrate, a pad bath containing the desired component is preparedeither by direct addition of the individual components to water or bydilution of a high solids (30 percent, for example) dispersion. Thesolids content of the pad bath is adjusted so as to obtain about 0.5 to5 percent (1 to 3 percent preferred) addon of finish on the fabric whendried. in order to accelerate the curing or crosslinking reaction whichinsolubilizes the finish on the fabric, it is necessary to include anacid or a latent acid catalyst in the pad bath. Generally, from 0.5 to 3percent (based on weight of solids in the pad bath) of catalyst issufficient to effect a cure under typical textile processing conditions.The optimum catalyst concentration depends upon the catalyst used, thenature of the amino resin, and the time and temperature of curing.Examples of such suitable catalysts which may be used to promote thereaction of the amino resin with the hydroxy or carboxy groups availablein the dispersion are well known in the art and includep-toluenesulfonic acid, citric acid, glycolic acid, oxalic acid, aminehydrochloride, zinc fluoborates, and

solids). To 500 g. of the diluted formulation is added 0.45 g. of citricacid (3% catalyst based on weight of bath solids).
